"The Christian religion," wrote Robert Louis Wilken, "is inescapably ritualistic (one is received into the Church by a solemn washing with water), uncompromisingly moral ('be ye perfect as your Father in heaven is perfect,' said Jesus), and unapologetically intellectual (be ready to give a 'reason for the hope that is in you,' in the words of 1 Peter). Like all the major religions of the world, Christianity is more than a set of devotional practices and a moral code: it is also a way of thinking about God, about human beings, about the world and history."

Ritualistic, moral, and intellectual: May these words, ones that Wilken uses to begin his beautiful book, The Spirit of Early Christian Thought, be written on your soul as you begin college and mark your life—characterize and distinguish your life—for the next four years. The Christian fact is very straightforward: To be a student is a calling. You are privileged to enter a time— four years!—during which your main job is to listen to lectures, attend seminars, go to labs, and read books.

It is an extraordinary gift. We need you to take seriously the calling that is yours by virtue of going to college. You may well be thinking, "What is he thinking? I'm just beginning my freshman year. I'm not being called to be a student. None of my peers thinks he or she is called to be a student. They're going to college because it prepares you for life. I'm going to college so I can get a better job and have a better life than I'd have if I didn't go to college. It's not a calling."

But you are a Christian. This means you cannot go to college just to get a better job. Christians need jobs just like anybody else, but the years you spend as an undergraduate are like everything else in your life. They're not yours to do with as you please. They're Christ's.

Christ's call on you as a student is a calling to meet the needs of the Church, both for its own life and the life of the world. The Resurrection of Jesus, Wilken suggests, is not only the central fact of Christian worship but also the ground of all Christian thinking "about God, about human beings, about the world and history." Somebody needs to do that thinking—and that means you.

Don't underestimate how much the Church needs your mind. It takes an educated mind to do the Church's work of thinking about and interpreting the world in light of Christ. Physics, sociology, French literary theory: All these and more—in fact, everything you study in college—is bathed in the light of Christ. It takes the eyes of faith to see that light, and it takes an educated mind to understand and articulate it.

There's another dimension to the call of intellectual work. In the First Letter of Peter we read, "Always be prepared to make a defence to anyone who calls you to account for the hope that is in you" (3:15). Not everybody believes. Thus, the Church has a job to do: to explain why belief in the risen Lord actually makes sense. There's no one formula, no one argument, so don't imagine you will find the magic defence against all objections. You can, however, offer the reasonable defence Peter asks for. You may at least make someone think twice before he rejects the risen Lord.

Anyway, defence isn't the point. Lots of people feel lost because they imagine being a sophisticated, contemporary intellectual makes faith impossible. The Church wants to reach these people, but to do so requires an ambassador at home in the intellectual world. That's you—or at least that's what you can become if you do your work with enthusiasm. Share in a love of learning. It's a worthy love in its own right, and it will allow you to be the leaven in the lump of academia.

So, yes, to be a student is to be called to serve the Church and the world. But always remember who serves what. Colleges focus on learning; as they do so, they can create the illusion that being smart and well educated is the be-all and end-all of life. You do not need to be educated to be a Christian. That's obvious. After all, Christ is most visible to the world in the person who responds to his call of "Come, follow me." Your Christian calling as a student does not require you to become a theologian, at least not in the official sense of the word. But there is a wider sense of being a theologian, one that simply means thinking about what you are learning in light of Christ. To become a Christian scholar is more a matter of intention and desire, of bearing witness to Christ in the contemporary world of science, literature, and so forth.

You can't do this on your own. You'll need friends who major in physics and biology as well as in economics, psychology, philosophy, literature, and every other discipline. These friends can be teachers and fellow students, of course, but, for the most part, our intellectual friendships are channelled through books. C.S. Lewis has remained popular with Christian students for many good reasons, not the least of which is that he makes himself available to his readers as a trusted friend in Christ. That's true for many other authors too. Get to know them.

Books, moreover, are often the way in which our friendships with our fellow students and teachers begin and in which these friendships become cemented. Read Plato, Aristotle, Hume, and John Stuart Mill, and not just because you might learn something. Read them because doing so will provide a sharpness and depth to your conversations. To a great extent, becoming an educated person means adding lots of layers to your relationships. Sure, going to the big football game or having a beer (legally) with your buddies should be fun on its own terms, but it's also a reality ripe for analysis, discussion, and conversation. Think of books as the fine threads of a spider's web. They link and connect.

This is especially true for your relationships with your teachers. You are not likely to become buddies with your teachers. They tend to be intimidating. But you can become intellectual friends, and this will most likely happen if you've read some of the same books. Books are touchstones, common points of reference. They are the water in which our minds swim.

You cannot and should not try to avoid being identified as an intellectual. The word is often associated with people who betray a kind of self-indulgence, an air that they do not need to justify why they do what they do. Knowledge for knowledge's sake is the dogma used to justify such an understanding of what it means to be an intellectual. But if you're clear about your calling as a student, you can avoid this temptation. You are called to the life of the mind to be of service to the gospel and the Church. Don't resist this call just because others are misusing it.

Fulfilling your calling as a Christian student won't be easy. The curricula of many colleges and universities may seem, and in fact may be, chaotic. Moreover, there is no guarantee that you will be encouraged to read. Some classes, even in the humanities, are based on textbooks that chop up classic texts into little snippets. You cannot become friends with an author by reading half a dozen pages. Finally, and perhaps worse because insidious, there is a strange anti-intellectualism abroad in academia. Some professors have convinced themselves that all knowledge is just political power dressed up in fancy language, or that books and ideas are simply ideological weapons in the quest for domination. Christians, of all people, should recognize that what is known and how it is known produce and reproduce power relations that are unjust, but this does not mean all questions of truth must be abandoned. As I said, it won't be easy.

You owe it to yourself and to the Church not to let the incoherence, laziness, and self-critical excesses of the contemporary university demoralize you. Be sure not to let these failures become an excuse for you to avoid an education—a Christian education. Although some universities make it quite easy to avoid being well educated, I think you will find that every university or college has teachers who deserve the titles they've been given. Your task is to find them.

But how can you find the best teachers? There are no set principles, but I can suggest some guidelines. First, ask around. Are there professors who have reputations as intellectual mentors of Christian students? You're eighteen. You don't need substitute parents—or, at least, you don't need parents who think you are still twelve. But you do need reliable guides. So rearrange your schedule to take the professor who teaches Dante with sensitivity to the profound theological vision of that great poet. You may end up disagreeing, both with the professor and with Dante, but you'll learn how to think as a Christian.

Also, go to the bookstore at the beginning of the term to see which professors assign books—and I mean real books, not textbooks. Textbooks can play a legitimate role in some disciplines, but not in all, and never at all levels. You want to find the teachers who have intellectual friends, as it were, and who want to share those friends with their students.

The best teachers for a Christian student aren't always Christians. In fact, a certain kind of Christian teacher can lead you astray. The temptation is to compartmentalize, to assign your faith to the heart, perhaps, and then carry on with your academic work. Some professors have become very comfortable with this compartmentalization, so be careful. By all means take spiritual encouragement wherever you can get it; these sorts of professors can be helpful in that regard. But don't compartmentalize, because that's basically putting your Christian faith outside of your work as a student. Although many professors are not Christians (at some schools, most aren't), many professors have a piety especially relevant to the academic life.

One, for example, might be committed to the intrinsic importance of knowing Wordsworth's poetry, while another works at getting the chemistry experiment right. These professors convey a spirit of devotion. Their intellectual lives serve the subject matter rather than treating it as information to be mastered or, worse, a dead body of knowledge to be conveyed to students. This spirit of devotion is not the same as Christian faith, but it can help shape your young intellectual desires and impulses in the right way by reminding you that your job as a student is to serve and not to be served. College isn't for you; it's for your Christian calling as an intellectual.

It is also important that you not accept as a given the categorizations that dominate the contemporary university. I emphasize broadening your major with historical questions and challenges to set categories because your calling is to be a Christian student, not a physics student or an English student. It is important for you to interrogate theologically what you are learning. For example, you may major in economics, a discipline currently dominated by mathematical models and rational-choice theories. Those theories may have some utility (to use an economic expression), but they also may entail anthropological assumptions that a Christian cannot accept. You will not be in a position even to see the problem, much less address it, if you let your intellectual life be defined by your discipline.

There's more to say, and I wish I could give more practical, concrete advice. But most of academic life is "local," as Tip O'Neill once said of politics. For some students, studying with a professor who avows atheism may be their first encounter with a teacher who thinks faith is relevant to the intellectual life, albeit in a purely negative way. The encounter need not harm the Christian student. It might galvanize the student's convictions and set him or her on the course of figuring out how faith supports and motivates the intellectual life. Still, as I have tried to emphasize, you need good mentors—men and women who are dedicated to their work and for whom a fitting humility about the limits of their expertise leads them to read broadly and thus become intellectuals rather than specialists.

Let me return to Robert Wilken's observation about the ritual, moral, and intellectual life of the Christian. Don't fool yourself. Only a man or woman who has undergone a long period of spiritual discipline can reliably pray in the solitude of a hermitage. You're young. You need the regular discipline of worship, Bible reading, and Christian fellowship. Don't neglect them in college. Also, don't underestimate the moral temptations of the contemporary college scene. We cannot help but be influenced by the behaviour of our friends, so choose wisely.

To worship God and live faithfully are necessary conditions if you are to survive in college. But as a Christian you are called to do more than survive. You are called to use the opportunity you have been given to learn to construe the world as a creature of a God who would have us enjoy—and bask in—the love that has brought us into existence. God has given your mind good work to do. As members of the Church, we're counting on you. It won't be easy. It never has been. But I can testify that it can also be a source of joy.

What a wonderful adventure you have before you. I wish you well.

Professor Hauerwas has sought to recover the significance of the virtues for understanding the nature of the Christian life. This search has led him to emphasize the importance of the church, as well as narrative for understanding Christian existence. His work cuts across disciplinary lines as he is in conversation with systematic theology, philosophical theology and ethics, political theory, as well as the philosophy of social science and medical ethics. He was named "Americaâ€™s Best Theologian" by Time magazine in 2001. Dr. Hauerwas, who holds a joint appointment in Duke Law School, delivered the prestigious Gifford Lectureship at the University of St. Andrews, Scotland in 2001.
